University/Electro Voice?

[alteclipsch]

These look like Electro Voice cabinets but are holding University Mustangs. Has anyone seen these before or they a dyi replacement?

I saw that, I've read that you could buy empty factory cabinets from EV to install drivers of your choice. Maybe Mustangs were a common choice for these.

Purchasing separate cabs and drivers was a common practice in the early days of high fidelity and stereo. There was a lot of experimentation going on back in the day.
